"We came here prepared to play and win a game of footy, and we were 20 (points) up at three-quarter time and we expect to win that game and we didn't.

"I thought we lost control of the ball and lost control of field position … and, as we know in games, and late in games in particular, when fatigue is in play field position is vital and we didn't hold it and didn't retain it."

The Bombers' triumph was even more meritorious given it lost Zach Merrett to concussion before quarter-time.

It was Merrett's second concussion inside a month after copping a stray elbow from premiership Tiger Kamdyn McIntosh in the clubs' opening JLT Community Series match.

Merrett only moments earlier caught Douglas holding the ball, sparking a heated face-off between the pair at the opposite end of the ground.

Both teams fielded fresh faces and it was one who had to wait so long to become an Adelaide footballer who helped ignite the contest.

Ex-Blue Bryce Gibbs transformed a drab affair on the scoreboard into an explosion of goals with two in the first five minutes of the third quarter as the expected shoot-out finally eventuated.

These teams made scoring look easy in 2017, but it took until that third term for the dam wall to bust open as the Crows piled on seven goals to three to charge into a winning position.

The high-octane quarter shot the Crows 20 points ahead at the final change after the sides shared only nine majors in the opening half.

Gibbs was one of four debutants for Adelaide, along with impressive draftee Darcy Fogarty, Tom Doedee and Lachlan Murphy. Fogarty recorded a goal with his first kick while Murphy also hit the scoreboard.

But most interest was focused on Essendon's three-pack of recruits – Jake Stringer, Devon Smith and Adam Saad – who all had an impact on occasion.

Saad kept Eddie Betts goalless, Stringer took a huge early intercept grab and had 10 of his 16 touches in the first half and Devon Smith (23) impressed with his defensive pressure.

MEDICAL ROOMEssendon: Zach Merrett has now suffered three concussions in recent times, which is obvious reason for concern. Coach John Worsfold was reluctant to comment too much on his young star's condition, but he must be in serious doubt for next week.

Adelaide: Oft-injured Crow Curtly Hampton could be set for another stint on the sidelines after hurting his groin on Friday night. He was unsighted at AFL level after round nine last year because of a serious ankle issue in what was then the latest in a long string of ailments. Adelaide was unsure post-match of how bad Hampton's groin issue was.

NEXT UPThe Crows face a six-day turnaround as they prepare to host first-up winners Richmond in a much-anticipated Grand Final rematch at Adelaide Oval on Thursday night. A loss would leave them in unfamiliar territory at 0-2. Essendon has a much kinder eight-day break before travelling west to take on Fremantle at Optus Stadium.
